Inventors and Scientific Discoveries

Louis Pasteur discovered that heating liquids like milk to a specific temperature kills harmful bacteria, a process now known as pasteurization.

Thomas Edison is credited with developing the first commercially practical incandescent lightbulb. While others worked on similar technology, Edison's design was the first to be widely adopted.

Dmitri Mendeleev created the first version of the periodic table of elements. He organized elements by atomic weight and left gaps for elements that had not yet been discovered.

Benjamin Franklin is famous for his kite experiment, which demonstrated the electrical nature of lightning. While he did not invent electricity, his work was foundational to the scientific understanding of it.

James Clerk Maxwell formulated the classical theory of electromagnetic radiation, bringing together electricity, magnetism, and light as manifestations of the same phenomenon and predicting the speed of light.

James Watt is best known for his improvements to the steam engine, specifically the development of the rotary steam engine, which allowed steam power to be used for manufacturing and industrial applications.

Michael Faraday discovered electromagnetic induction in 1831, which is the fundamental principle behind the electric generator. While others improved upon his design, he is credited with the invention.

William Buckland, a professor at Oxford, published the first scientific description of a dinosaur, Megalosaurus, in 1824.

Gregor Mendel, an Augustinian monk, is known as the father of genetics for his pioneering work on inheritance patterns in pea plants.

• The first person to see a living cell under the microscope was Antonie van Leeuwenhoek. 
• He called that cell as animalcule. He is commonly known as "the Father of Microbiology", and considered to be the first microbiologist. 

• The cell is the basic structural and functional unit of life. Schleiden proposed that new cells arise from within the old cells, especially from the nucleus. 
• This was corrected by Rudolf Virchow who proposed, "Theory of cell lineage" it states that all cells arise from pre-existing cells.

• Robert Hooke discovered cell in the year 1665. He observed cork cell in the bark of Spanish oak tree under a simple microscope and was able to see the empty structures surrounded by walls and named it a cell. 
• He elucidated his observation in a book called "Micrographia.

The well-known scientist Robert Brown discovered the nucleus in the year 1831. 

The invention of the microscope allowed the first view of cells. English physicist and microscopist Robert Hooke (1635–1702) first described cells in 1665. He made thin slices of cork and likened the boxy partitions he observed to the cells (small rooms) in a monastery. The open spaces Hooke observed were empty, but he and others suggested these spaces might be used for fluid transport in living plants. He did not propose, and gave no indication that he believed, that these structures represented the basic unit of living organisms.
